This information is bit incomplete, I must say that the homework was done really good, but the problem came when you tried to assemble this information and present it. No doubt you did your best and I appreciate the fact that this will help as well, you should read other posts as well to make your posting really to the point and really understandable. I will PM you some of the threads about this topic so that the next time you visit the forum and post something really informative like this, it will be more effective and helpful to all.
